Proguard用DNSJava库混淆Android代码

Question

我有一个Android应用程序,在项目的/ libs /目录中有dnsjava.jar.一切都很好,可以打包成APK(没有proguard).

但是,当我将proguard引入project.properties(在eclipse中)时,我收到以下警告:

[2013-03-07 14:16:08 - ] Proguard returned with error code 1. See console
[2013-03-07 14:16:08 - ] Warning: org.xbill.DNS.spi.DNSJavaNameServiceDescriptor: can't find superclass or interface sun.net.spi.nameservice.NameServiceDescriptor

[2013-03-07 14:16:08 - ]    at proguard.Initializer.execute(Initializer.java:321)

使用-keep class org.xbill.**{*; 在proguard-project.txt中似乎没有解决这个问题.

已通过proguard和DNSJava测试。希望能帮助到你。从asmack自述文件复制

# This dnsjava class uses old Sun API
